BENCH FCR CIRCULAR SAWS.

SPECIFICATION forming part of Letters Patent No.380,560, dated April 3, 1888.

Application filed Septemberll, 1887. Serial No. $50,045. (No model.)

T0 aZZ whom it may concern:

Be it known that I, FREDERIC E. FARWELL, of Fitchburg, in the county of "Worcester, State of Massachusetts, haveinvented certain new and useful Improvements in Benches for Circular Saws, of which the following is a description sufficiently full, clear, and exact to enable any person skilled in the art or science to which said invention appertains to make and use the same, reference being had to the accompanying drawings, forming part of this specification, in which- Figure l is a vertical longitudinal section of a saw-bench provided with my improvement, represented as in use, certain parts being shown in side elevation; Fig. 2, a vertical transverse section of the same, taken on line rv a: in Fig. l; and Fig. 3, an elevation showing certain details of construction.

Like letters ofreferenceindicate corresponding parts in the different figures of the drawings.

My invention relates more especially to means for adjusting the table of a bench; and it consists in a novel construction and arrange ment of parts, as hereinafter more fully set forth and claimed, the object being to produce a simpler and more effective device of this character than is now in ordinary use.

The nature and operation of the improve ment will be readily understood by all conversant with such matters from the following explanation.

In the drawings, A represents the body or frame of the bench, B the table, and C the circular saw.

The body is of the form and construction usual in benches of this description, the saw C being journaled on a shaft, m, in said body and driven by any suitable means. The table B is hinged atm to the rear end of thebody A, and is provided with a slot, z, through which the saw G protrudes.

Journaled on bolts c to each of the side timbers, d, of the body A, in front of the saw C, there is an upwardly-projecting arm or plate, g, the upper edge of which is rounded, as shown atz'in Fig. 1. These plates are con nected at their lower ends by a cross-bar, h, on the upper side of which are disposed standards t, in which is journaleda roll, k.

Secured to the inner face of the front crosstimber, l, of the body there is a downwardlyprojecting bracket, p, (see Fig. 4,) in the lower end ofwhichis pivoted ahorizontally-arranged tubular box, r. A rod, w, is mounted in this box, said rod being provided at its outer end with a handwheel, D, by means of which it may be revolved. The rod w is screwthreaded at its inner end and enters a screw-threaded hole, b, (see Fig. 2,) formed centrally in the roll lc, said roll serving as a nut for said screw.

To the under side of the table B are secured longitudinallyarranged grooved tracks or ways H, so arranged that the tops "L of the plates g will slide therein.

In the use of my improvement it will be obvious that by turning the wheel D to the right or left the roll 7a will be caused to travel on the rod w and the plates g to swing on the bolts c, the upper ends of said plates being moved back and forth in the tracks E, thereby causing the table B to be raised or lowered, as the case may be.

Having thus explained my invention, what I claim isl. In a saw-bench, the table B, provided with the grooved tracks H and hinged to the body A, in combination with the plates g, pivoted to said body and having their upper ends disposed in said tracks, and a screw for actuating said plates and raising and lowering the table, said screw working in a support on the frame-work of the machine and in a pivoted roll .or nut connected with said plates, substantially as set forth.

2. In a saw-bench, the plates y, connected by the bar Il. and pivoted to the body A, the standards t, mounted on the bar h, the roll 1c, journaled in said standards and provided with the screw-threaded hole b, the tubular box r, pivoted in the bracket 1:, the screw-threaded rod w, mounted in the tube 1- and provided with the Wheel D, and the table B, hinged to the body A and provided with the grooved ways H, all being constructed, combined, and arranged to operate substantially as set forth.

FREDERIC E. FARVVELL.
